Given the current US Airways transfer promotion and bonus for preferred, I'll be the first to ask:
any recent luck getting US Airways status matches, or any recent news on some of their "Race to preferred" or "preferred trial" promotions?
EDIT: Just spoke to US Airways.
They do not match, but they did currently offer the 90 day trial preferred membership for anyone who has not dropped down from status in the past 24 months. Unfortunately, because I took advantage of that USAirways/Budget Rental free preferred trial last summer, I'm not eligible, and they were pretty strict on it.
Details, if you are eligible: seems to have $15 fee, silver preferred good for 90 days, need to fly 7,500 miles to maintain it within 90 days.
EDIT Seems to be a YMMV on the $15 fee. Others are reporting $200, though I was quoted if I had been eligible it would've only been $15.
